NI Speed with various Athlon processors - your experiences?

[Greg Campbell]

Those running ver 4.0 and wanting to compare a 'standard' image + profiles configuration can download the files from http://members.cox.net/geonerd/nitest.zip
Dial up users note - the file is over 4MB.

It's a B/W image, but uses all the filter frequencies, USM, and other goodies. I'll cook up a color benchmark when I get a chance.


My times:

PC #1
AMD T'bird at 133 x 9 = 1.2 gigahertz
512M PC 133, Cas2
KT133a chipset. 4 way memory interleave.
Time: 2:07

PC #2
AMD XP 1700+ (Thoroughbred core) at 1.75 GHz (175x10)
NForce2 chipset, dual bank, 512 MB at 175/350 MHz. Cas 2.5
Time: 0:50

C'mon you A64 and 4 gig P4 users, lets see some speed!

Dual Opteron 244 (1.8 GHz), 2 GB DDR400 RAM (2-3-2-7, I think), AMD-8000 chipset

Time (1 image): 0m35s, 13.54 megapixels/minute
Time (2 images): 0m45s, 21.06 megapixels/minute

It's too bad NI can't work on a single image using multiple CPU's.

Same hardware as above, but now running 4.2 Pro+, and I'm doing a batch of 10 copies of the same image:

Time (10 images, processing only): 3m36s, 21.93 megapixels/minute
Time (10 images, loading + processing + saving): 3m52s, 20.42 megapixels/minute

A single image (thus only using one CPU) takes 30.5 seconds, or 15.53 megapixels/minute. So NI is only running at about 70% efficiency with two CPU's (it should do 31 megapixels/minute, but only gets about 22). I should try running two instances of NI to see if that makes a difference (I would expect not, but you never know)...

I'll continue this in a new thread...

Probably 100% efficiency is not achieved because of RAM speed limitation. If that is the case then running two instances of Neat Image should be as fast as running one that uses two CPUs.

BTW, are the images are all of the same size?

Yes, I actually duplicated the JPEG file on disk 40+ times so I could use the batch directory function. Exact same image over and over and over again.
